IDO-SOM2D01 is an ultra-small SOM module based on SigmaStar SSD201/SSD202
SoC (ARM Cortex A7 core). The module integrates WIFI, NAND and PM
circuits on a PCB area of 2.95CM x 2.95CM. The SoC integrates 128 MB of
DDR3 on-chip.
IDO-SBC2D06-V1B-22W is an dual-ethernet SBC powered by a IDO-SOM2D01,
that embeds a MicroSD card slot, 4-lane MIPI DSI connector for 4-inch
RGB565 display or 7-inch RGB888 display, Dual 10/100M Ethernet ports,
and more.
This series adds support for this SOM and this boards.
Changes since v2:
- Added Rob's acknowlegment
- Fixed warning with make dtbs_check regarding oneOf and the compatible
strings of the DTS board.
- Fixed commit short message format for the first commit
Changes since v1:
- Removed the commit that adds me as co-maintainer (merged)
- Fixed alphabetic order in dt-bindings
- Moved the commit that adds vendor prefix before adding the DT for the
board (re-ordered commits)
- Removed unneeded space

2.33.0
The Wireless Tag IDO-SBC2D06-V1B-22W[1] is an SBC powered by SSD202D
with a dual Ethernet and a connector for a 4-inch and 7-inch display.
It embeds a System-On-Module IDO-SOM2D01[2] with an Mstar SSD202 SoC
dual-core Cortex-A7 CPU @ 1.2Ghz , 2D GPU, 128 MB DDR3 (on-chip) and
a 256MB SPI NAND flash. This commit adds basic definition for this
board.
